CHARLES CHRIST, OF LYNDHURST, NEW JERSEY.

RULED TYPE-FORM AND METI-IGD OF AND APPARATUS FOR PRODUCING THE SAME.

Application filed August 24, 1918.

To all whom z'tmay concern:

Be it known that I, GHARLEs CHRIsT, a citizen of the United States of America, residing at Lyndhurst, county of Bergen, and State of New Jersey, have invented new and useful Improvements in Ruled Type-Forms and Methods of, and Apparatus for Producing the Same, of which the following is a specification.

My invention relates to matrices and type forms. 7

An objectof my invention is the provision of a method of and apparatus for forming slugs having novel means for retaining a printing rule thereon. 7

Another object of my invention is the provision of a novel form of slugs adapted to form when placed in juxtaposition a continuous channel having an upper edge adapted to be turned over by the operation of planing down.

In carrying out my method, I utilize the original matrices and modify their construction byproviding complementary depressions in any two adjacent matrices and between which is interposed a blank matrix or spacer. When the complementary matrices and intervening spacer are introduced to the mold of the machine, the molten metal flows into the depressions producing complementary upstanding projections on the slug, while the projecting edge of the blank prevents the flow ofmetal to and between the depressions, thereby forming a channel on the slug. The channel is adapted to receive a printing rule for securing a plurality of slugs together, while the projections retain the rule within the channel and secure the slug in type form. I provide various forms of projections all of which coact to lock the rules on the slugs against displacement vertically as wellas horizontally, so that the several slugs which comprise a type form are securely held together for printing.

I will describe three forms of matrices and slugs all embodying my invention, and will then point out the novel features thereof in the claims.

In the accompanying drawings, Figure 1 is a view showing, in perspective, one form of complementary matrices, embodying my invention.

Fig. 2 is a fragmentary view showing, in

perspective, one form of type form embody.-

ing my invention, the slugs of which are produced by the matrices shown in Fig. 1.

Specification of Letters Patent.

Serial No. 251,226.

a Fig. 5 is a fragmentary view showing, in

perspective, another form of type form embodying my invention, the slugs of which are produced by the matrices shown in Fig. 4f.

Fig. 6 is a transverse sectional view taken 011 the line VI-VI of Fig. 5.

Fig. 7 is a view similar to Fig. at, showing still another form of complementary matrices embodying my invention.

Fig. 8 is a fragmentary view showing, in perspective, a type form embodying my invention, the slugs comprising the same being produced by the matrices shown in Fig; 7.

Figs. 9 and 10 and 11 are fragmentary perspective views showing, on an enlarged scale, one form of my improved slug having different forms of rules secured therein. Figs. 10 and 11 illustrating, respectively, the rule and slug before and after the planing operation.

Similar reference characters refer to similar parts in each of the several views.

Referring to the drawings, and particu larly to Fig. 1, A and At designate two complementary matrices, the casting edges of whichare formed with the usual die cavities, 10, and the type dies, 11. In the present instance, the casting edges of the matrices A and A are beveled at opposite points from central line, as at 12 and 12, and because of the form of type of this particular matrix, such beveled edges occur at the left-hand end of each die cavity, 10. The matrices A and A are adapted to be assembled as shown, and interposed between the matrices is a blank matrix or spacer B. The spacer B is of the usual construction and when arflows from the mold when presented thereto,

while the projecting edge of the spacer provides a partition which divides the supplemental mold cavities. The slugs produced 7 width thereof.

as a result of this arrangement are shown in Fig. 2, wherein each slug, S, is provided with complementary tapering projections, P and P, formed by the beveled edges 12 and 12 coacting with the spacer B, and a transversely extending U-shaped channel, C, formed by the projecting edge of the spacer B. As clearly illustrated in Figs. 2 and 3, the projections P and P are below the surface of the type and the bottom of the channel C lies flush with the surface of the quad. Such a slug forms an efiicient means for securing and receiving a printing rule, against longitudinal as well as vertical displacement in the channel C, as will be hereinafter described.

Referring now to Fig. 1, I have here shown another form of complementary matrices, designated as A and A and having their casting edges formed with recesses or notches, 13, adjacent the type dies. As shown, the bottom walls of the notches 13 are disposed slightly above the bottom of the die cavities. When these matrices are arranged upon opposite sides of a blank matrix B, their recesses 13 presentmold cavities for the production of upstanding rectangular projections P on a slug S and upon opposite sides of a channel C, as shown in Fig.

In F 7 the matrices A and A are used for making slugs having lines for rule work. The casting edges of the matrices A and A are beveled for a major portion of their length, as at 14, to provide mold cavities for forming projections which are of a length corresponding to the width of the slugs. The V-shaped notch, 15, in each matrix A and A is the usual die for molding the line of type in one direction, while the blank matrix, B, between the matrices forms the channels C to receive the printing rule for molding the lines in the other direction. This arrangement of matrices and spacers produces the slugs S shown in Fig. 8, each of which is formed with a channel C and projections P and P which extend the entire The channels C and the projections P and P of all the slugs S are arranged in alinement to form a continuous channel, thereby providing an effective means for securing a print rule thereon against longitudinal and vertical displacement;

From the foregoing, it will be apparent that the shape of the projections P may be varied, the essential feature being that the vertical side walls and the horizontal bottom of the channels C are maintained. It is to be noted that all of the matrices A,

as well as the blank matrices B are the original matrices commonly used for forming the ordinary slugs, and that I have only modified the construction of the original matrices to form an improved form of slugs. This is an important feature of my invention as it eliminates the necessity of providing special forms of matrices to produce the desired slugs, as these matrices may be used in ordinary work without any possibility of the beveled edges or depressions interfering with the production of the usual slugs.

Various forms of printing rules may be used in the channels C for securing a plurality of slugs together to provide a type form. However, in the present instance 1' have shown only two forms of printing rules which will exemplify the utility of the various forms of slugs.

lVhile I have described in detail the forms of matrices and slugs herein illustrated, it is to be understood that I do not thereby limit my invention to the precise features of construction shown, as I am aware that many mechanical changes and modifications may be made therein without departing from the spirit and scope of the invention as set forth in the appended claims.

I claim 1. A matrix having an elongated depression in its casting edge, a die depression formed within said elongated depression, and a depression also within said elongated depression adjacent to said die depression and of less depth than the latter.

2. A matrix having an elongated depres sion inits casting edge, a die depression formed within said elongated depression, and adepression also within said elongated depression adjacent to said die depression and having its bottom wall tapered from the longitudinal center of the matrix toward each side edge thereof.

3. The combination with apair of matrices of the form described in claim 1, of a blank interposed between the pair also having an elongated depression of the same depth as the elongated depression of the matrices.

4. The combination with a pair of 1natrices of the form described in claim 2, of a blank interposed between the pair and also having an elongated depression of the same depth as the elongated depression of the matrices, the blank cooperating to form with each matrix a depression having a vertical wall and a tapered wall.

In testnnony whereof I have signed my name to this specification.

CHARLES CHRIST.
